Near-Field Focusing Dielectric Resonator Antenna Array for Fixed RFID Readers

Abstract

The design of a NF-focused DRA phased array antenna is implemented for fixed RFID reader applications at 5.8 GHz. The radiated field is focused in the near-zone of the array aperture. Numerical investigations on the radiation characteristics of the NFfocused array as well as uniform phase array are presented to demonstrate its feasibility for RFID real applications.
